A ltorneys Patented July 4, 1939 UNITED sTATEs PATENT OFFICE 2 Claims.

The invention illustrated in the accompanying drawing and about to bedescribed and claimed, pertains to smoking pipes, having reference inparticular to a flexible so-called, non-breakable joint betweencomplemental bowl and mouth stem units.

As implied by the introductory general statement of the invention, I amaware that flexible non-breakable joint constructions are not broadly mnew. Therefore, the subject matter under consideration pertains to whatis believed to be an improved joint construction, the same beingcharacterized by companion bushings keyed together,

the bushings being arranged to accommodate a l" special nltering memberand an associated jointing spring.

It is therefore the object of this invention to generally improve uponprior patented and marketed pipe joint constructions by adopting andassociating an assemblage of appropriate features aptly fitted toaccomplish the desired result and suitable in providing a simple andeconomical sectional pipe stem construction.

Other features and advantages may become apparent from the followingdcription and the accompanying drawing.

In the drawing, wherein identical reference numerals designate anddistinguish identical parts:

Figure 1 Ais a side view of what appears externally as a conventionalsmoking pipe, portions thereof being broken away and shown in section toreveal the details and arrangements of the improved separable butnon-breakable joint.

Figure 2 is an enlarged fragmentary elevational view disclosing theconstruction and connection of the companion threaded bushings.

Figure 3 is an enlarged longitudinal sectional view through the smokeregulating and filtering stud or unit.

Figure 4 is an enlarged cross section on the line 4-4 of Figure 1.

In the drawing, the bowl section 5 includes a hollow stem portioncooperable with the complemental mouthpiece or stem portion 6. Theabutting end portions are hollowed out to provide the desired chamber toaccommodate the mechanism of the invention. Adjacent the abutting endsthe parts 1 and 8 are internally screw-threaded to allow the companionbushings 9 and I0 to be screwed in place. The collar II on the bushing 9is provided with circumferentially spaced keeper or retention notches I2receiving detent lugs or keys I3 on the corresponding collar portion I4of the bushing I0. This provides the desired interlocking feature topermit the bushings to be separated in an endwise direction while at thesame time preventing relative rotation.

The headed filtering stud unit I5 embodies a shank I6 with a terminalhead I1 the shank being tapered and provided with a shoulder formingflange I8. Beyond this the structure is formed into a threaded extensionI9. The smoke intake port or orifice 20 communicates with the smokeconveying bore or passage 2|.

It is to be noted that the unit I5 is supported in the bushing 9. vThatis to say, the abutment flange I8 rests against one end of the bushingwhile the threaded extension I9 projects into the bushing. The threadson the stem serve to accommodate the convolutions or coils on one end ofthe coiled spring 22. The spring extends on through both bushings andthe coils at the opposite end are held in place by inwardly projectingor radial detents 23 carried by the adjacent end portion of the bushinglil. Thus the detents 23 are threaded home on the coils of the spring toput the spring under tension and to thus flexibly adjon the two bushingstogether. The resiliency of the spring is obviously such as to permittwo sections or units 5 and 6 of the pipe to be pulled apart under duestress and strain so that by proper manipulation the coils of the springtend to clean and dislodge accumulations such as might collect in thebushings. Moreover, by thus separating the sections 5 and 6 sufficientlyto disconnect the keys I3 from the keeper notches or keyways I2, thesection 6 can be backed off of the spring to completely disjoin theparts for repair or cleaning.

It is thought that the description taken in connection with the drawingwill enable a clear understanding of the invention to be had. Therefore,a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown anddescribed, it is to be understood that minor changes coming within thefield of invention claimed may be resorted to if desired.

I claim:

l. In a smoking pipe construction of the class described, a bowl havinga stem portion, a complemental stem portion provided with a mouthpiece,adjacent ends of said stem portions being disposed in separable abuttingrelationship, companion bushings fitted into the respective stemportions, the adjacent ends of said bushings being separably keyedtogether.

2. As a new article of manufacture and a comjecting into the rst namedbushing, a coiled spring having predetermined convolutions fastened onthe threads of said extension, the convolutions at the opposite end ofsaid spring being cooperable with said detents in the manner and 5 forthe purposes described.
